ownership - Compaq ownership tag retriever
ownership retrieves and prints the "ownership tag" that can be set on Compaq computers. Contrary to all other programs of the dmidecode package, ownership doesn’t print any version information, nor labels, but only the raw ownership tag. This should help its integration in scripts.
